Parity does exist in the NFL, but after a month of football, more than three teams remain undefeated with no marks in the loss column.
The incredible thing is at least three teams will remain undefeated after Week 5 has concluded as well.
Whether it's a favorable matchup or other factors, the following three teams are guaranteed to take perfect records into Week 6. They may not be the only teams to perform the feat, but the following teams are locks.
New England Takes Advantage of Cincinnati Secondary
The Cincinnati Bengals were upended by the Cleveland Browns in Week 4 while starting safety Reggie Nelson and cornerback Leon Hall missed the game due to injuries. The ensuing result was Cleveland backup Brian Hoyer throwing for 269 yards and two touchdowns.
Regardless of whether or not Newman and Nelson are good to go against New England, Tom Brady will have little issue picking apart the Bengals secondary. Each quarterback the defense has faced has tallied in the neighborhood of 250 yards.
Much of the reason for the struggles is simple—starting corner Terence Newman is older, and Adam Jones has been picked on this year. Add in injuries and thin depth and Brady should have little issue hitting the 300-yard mark with a pair of touchdowns.
The main obstacle for Brady is a strong Cincinnati defensive line, but Brady has been sacked just seven times thanks to his quick release. Brady understands Cincinnati'a weak point is the secondary, and he'll be sure to take advantage.
Prediction: Patriots 35, Bengals 21
Seattle Outlasts Indianapolis
Seattle moving to 5-0 is not all that shocking, but moving past the Indianapolis Colts is far from a sure thing.
Both Seattle and Indianapolis have notched wins over the defending NFC Champion San Francisco 49ers in recent weeks and enter the matchup undefeated. Both also tout top-10 rushing attacks and pass defenses.
Seattle may have to travel away from its comfort zone at home, but Marshawn Lynch will be able to make some noise on the ground against a Colts defense that gives up 107 yards per game.
Not only will Seattle be able to control things on the ground, but the defense will also hold Andrew Luck and Co. in check thanks to the NFL's best pair of corners—Brandon Browner and Richard Sherman, a duo that has held passers to 191 yards per game.
It's been a great three-week undefeated run for Indianapolis, but it comes to an end in Week 5.
Prediction: Seahawks 35, Colts 30
Kansas City Dominates Tennessee Titans
Believe it or not, the Tennessee Titans are quietly one of the NFL's better teams thanks to a much improved defense that ranks in the top 10 against both the run and pass.
Conversely, under new head coach Andy Reid the Kansas City offense touts one of the most balanced attacks and dictates the pace of each game, which has allowed the new era to start off in an undefeated manner.
Tennessee will need its stellar defense playing at a high level because the offense won't be much help. Starting quarterback Jake Locker went down in Week 4 and looks to be on the shelf for a while per NFL Network's Ian Rapoport.
Backup Ryan Fitzpatrick is no slouch, but Kansas City is elite against the pass, surrendering just 189 yards per game through the air. With the Kansas City offense methodically picking its way up and down the field, Tennessee won't have a lot of time to put points on the board.
Kansas City will remain undefeated and notch a big win while taking advantage of a weakened Tennessee roster.
Prediction: Chiefs 27, Titans 7
